Title: Improved device for controlling the pressure exerted by a tool on a workpiece
Inventor: PURCELL RICHARD D
IPC: B23Q5/26
Filed: 1954-04-27
Abstract: 783,341. Polishing. VAUXHALL MOTORS, Ltd. March 30, 1955 [April 27, 1954], No. 12084/54. Class 60. The pressure exerted by a rotary tool on a workpiece is maintained substantially constant by varying the effective weight of the tool, to compensate for variations in the pressure of the tool on the workpiece due to variations in the contour of the workpiece in a vertical plane, through the actuation of a valve by means of a cam constituted by the workpiece itself or forming part of or being carried by a fixture which supports the workpiece. Buffing, polishing, grinding and brushing are mentioned. A machine for polishing motor vehicle radiator grille bars or like workpieces 24 has a rotary polishing tool 1 carried by a polishing head 2 in the form of a pivoted arm. A chain 3 is attached at one end to the head 2 adjacent the free end thereof and passes over a sprocket 4 rotatable in fixed bearings in a support frame 5 ; from the other end of the chain is suspended a guide sleeve 6 formed with diametrically opposed slots 7 and carrying main counterweights 8. Below the open end of the guide sleeve 6 is an air cylinder 9 secured to base plate 10 by tie rods 11 and having a piston 12 extending into the guide sleeve 6 adjacent the slots 7. In the slots 7 is a slidable rod 13 the outer ends of which carry auxiliary counterweights 14. The air cylinder 9 is controlled by a valve 15 having a control lever 21 actuated by a cam 22 on a fixture 23 which carries the workpiece. When the valve 15 is not engaged by the cam 22 air is admitted to lower the piston 12, both the main and auxiliary counterweights 8, 14 being effective since the rod 13 rests on the lower ends of the slots 7. When the cam 22 actuates the valve 15 compressed air is admitted to raise the piston 12 which then supports the rod 13 and auxiliary counterweights 14, so that only the main counterweights 8 are effective. If there is more than one change in contour of the workpiece 24 the cam 22 can be designed to operate the valve 15 in successive stages, a weight being added to or removed from the total counterweight at each stage. The sleeve 6 can be formed with a series of pairs of stepped shoulders in the slot, each pair carrying a rod on which are counterweights and the piston 12 can be arranged to pick up rods at successive stages of valve movement. Alternatively two or more pistons could be used to pick up or replace the rods at various stages. A flow regulator may be fitted in the compressed air supply line to control piston speed and avoid undue shocks.

Abstract: 1,214,274. Fluid cooling heat exchangers. J. G. SATTERTHWAITE and J. B. MACY JNR. 7 March, 1969 [8 March, 1968], No. 12184/69. Heading F4S. A heat exchanger intended for mounting on the exterior of the hull 10 of a marine vessel so that a liquid such as water from the vessel's power plant may be cooled by circulation through the heat exchanger by way of connections 21, comprises tubes 13 extending between box-shaped headers 11, 12. Each header is made of a relatively rigid elastomeric material, and consists of two or more sections e.g. 27, 28, 29, placed face to face and clamped together e.g. by bolts (26, Fig. 3), each section having recesses e.g. 43, 46, 47, 48 respectively therein which co-operate to provide openings in which the tube ends are received. A sealing element e.g. 51 is placed on the end of each tube and is sized so that it is gripped tightly in the opening when the header sections are clamped together. The clamping screws pass through co-operating holes in the sections and are screwed into plates 22, 23 welded to the hull 10. A partition 66 may be provided the position of which can be selected according to requirements using slots 69 in the header sections. By this means the header can be made to function as a divided header, or as a return header (by omitting the partition). In other arrangements described, by partitioning both headers the tube assembly may be divided into two separate tube groups for cooling two different fluids. In a further arrangement, tubes may extend from two or more sides of the header box. The tubes 13 may be fluted as shown, or cylindrical.

Title: Improvements in character display arrangements
IPC: H04L21/00
Filed: 1959-04-10
Abstract: 900,929. Cathode-ray tube circuits. STANDARD TELEPHONES & CABLES Ltd. April 10, 1959 [April 16, 1958], No. 12215/59. Addition to 830,804. Class 40 (7). A character display arrangement wherein each character is formed on an array of areas of a display device by exciting a selected combination of areas comprises a source of information representing characters, a counting arrangement having an output individual to each area of the array, a first diode matrix having a set of inputs coupled to the information source for receiving a pulse train representative of any one of the characters, each matrix output being individual to a different one of the characters, gating means coupled between the outputs from the matrix and the display device, and a second diode matrix having a set of inputs coupled to separate outputs from the counting arrangement and having outputs coupled to the gating means, each output of the second matrix being individual to a different character and adapted to pass to the display device the pulse combination for that character when the gating means is conditioned in a manner significant to that character. The embodiment relates to the display of characters on a cathode-ray tube (C.R.T.) screen by the intensity-modulation of the C.R.T. beam at the requisite points of a 5Î7 raster, Fig. 8. In the circuit diagram all lines shown interconnecting rows and columns of a matrix contain a diode poled in the same direction as those shown. Each character is represented by a six-bit code from bi-stable devices (not shown) and coupled to inputs 31 ... 36 of matrix 30; and each character has its own row of matrix 24. Assume that character 2 is to be displayed. Corresponding binary code 111000 ensures that row 37 only carries a positive voltage, derived from line 38, to the base of corresponding transistor gate 39; the gate outputs are fed to C.R.T. grid amplifier 18a. In the absence of positive voltage input to the collector of transistor 39 that gate is closed. Clock pulses from generator 11 progressively switch over the bi-stable units of counters 12 and 13; as the blanked and stepped 5x7 raster is being formed by generators 16, 19, matrices 21, 22 and 23 feed into the columns of matrix 24. The columns of matrix 23, proceeding from left to right, correspond to the successive points of the 5x7 raster and transistor gate 39 opens for unit pulse intervals according to the diode column/row connections depicted for numeral 2, thus producing the display according to Fig. 8. Counter 14 is provided to shift the raster bodily and progressively to the right to enable writing of a line of characters; and counter 15 similarly steps the display downwards line by line. Matrix 24 may be a plug-in sub-assembly to enable character display in other languages or display of, e.g., weather symbols. It is stated that the apparatus is specially suitable for airborne displays.

Abstract: 183,910. Wolff, A. L. April 28, 1921. Spray carburettors.-Fuels of different grades are admitted separately or in combination to the float chamber under the control of a valve actuated by a thermal device in the cylinder wall. Fuel from the float chamber 9 passes a valve 26 into a chamber 8 the air supply to which is controlled by a valve 30, the resulting mixture entering the cylinder by a valve 2. The fuels, which may be ether through pipe 15, gasolene through pipe 16 and kerosene through pipe 17, are admitted to the interior of a hollow spindle 11 and thence to the float chamber 9 through a port 18 in the spindle. The spindle together with the valve 26 is actuated from a rod 4 with high coefficient of expansion located in the cylinder wall 3, through a lever 5 loaded by a spring 7 and connected to the spindle through an adjustable screw 21. The spindle has au internal rack which may be adjusted by hand if desired through a pinion 20. At starting, when the cylinder is cold, the port 18 is opposite the pipe 15 and ether is admitted. As the cylinder becomes warm, the rod 4 expands and depresses the spindle 11 to admit varying proportions of ether and gasolene, then gasolene and kerosene, and finally kerosene only. During the downward movement of the spindle 11 the port 18 is kept in register, and during the upward movement out of register, with the pipes 15, 16, 17, by means of a pin 22, Fig. 3, on the spindle engaging grooves 23, 24 in the spindle casing 10, the pin being prevented from entering the wrong groove by pawls 101, 102. A slide 12 attached to the spindle 11 moves over a port 13 in the float chamber to ensure that fuel is drawn from that level corresponding to the density of the fuel in use.
